May also be interested in the `jq` CLI, which on first glance appears to use a similar but not identical query language. https://stedolan.github.io/jq/

Also this tool is pretty interesting: https://github.com/chrisdone/jl

How do this query language compares to jq?

seconded. the jq language is surprisingly powerful and at first glance at jmespath, the syntax is similar.

I think the equivalent jq query would be something like:

    [.locations[] | select(.state == "WA").name] | sort | join(", ") | { WashingtonCities: . }

I'd rather use App::RecordStream.
